The length of a potentiometer wire is l. A cell of emf E is balanced at a length `l/3` from the positive end of the wire , If the length of the wire is increased by `l/2` ,the same cell gives a balance point at a length of `l/k`. The value of k is `_`

The length of a potentiometer wire is l . A cell of emf E is balanced at a length l/3 from the positive end of the wire. If the length of the wire is increased by l/2. At what distance will the same cell give a balance point.

If the resistance of potentiometer wire is 15r then calculate the balance length l

The length of a steel wire is l_(1) when the stretching force is T_(1) and l_(2) when the stretching force is T_(2) . The natural length of the wire is

In a potentiometer arrangement, a cell of emf 2.25V gives a balance point at 30.0 cm length of the wire. If the cell is replaced by another cell and the balance point shifts to 60.0 cm, then what is the emf of the second cell?

In a potentiometer arrangement a cell of emf 1.5 V gives a balance point at 30 cm length of wire. Now, when the cell is replaced by another celle , the balance point shifts to 50 cm. What is the emf of second cell ?

Figure shows a potentiometer circuit, a cell of emf E_1 is balanced by length l' of the potentiometer wire. If this cell is replaced by another of emf E_2 , it is found that total length of potentiometer wire has to be increased by 50%, in order to have the same balance length (l'). Then E_1//E_2 is______.

Figure shows a potentiometer circuit, a cell of emf E_1 is balanced by length l' of the potentiometer wire. If this cell is replaced by another of emf E_2 , it is found that total length of potentiometer wire has to be increased by 50%, in order to have the same balance length (l'). Then E_1//E_2 is______.

In a potentiometer arrangement , a cell of EMF 2 V gives a balance point at 40 cm length of the wire . If this cell is replaced by another cell and the balance point shifts to 60 cm , then the EMF of the second cell is

In a potentiometer arrangement, a cell of emf 1.25 V gives a balance point at 35.0 cm length of the wire. If the cell is replaced by another cell and the balance point shifts to 63.0 cm, what is the emf of the second cell ?

In a potentiometer a cell of emf 1.5V gives a balanced point 32cm length of the cell is replaced by another cell then the balance point shifts to 65.0cm the emf of second cell is
